Trayvon Martin's girlfriend - the state's star witness - testified today about the last phone call he made before he was shot dead in which he described George Zimmerman following him.

Rachel Jeantel, 19, told the court she asked the teen what the man looked like and he said he looked creepy, 'a creepy-a** cracker'.

She said Trayvon told her he was going to go home but the man was still following him, saying 'Oh sh**, the n**** is still behind me'.

'I just told him to run,' Rachel told the court, adding that she heard a 'hard-breathing man' in the background.

The pair then got cut off and when she called him back he told her he was back at his father's fiancee's house and he thought he had lost the man.

'It was about to rain when he was going
to 7-Eleven', said Jeantel. They talked about the All-Star game which Trayvon left at halftime to go to the store.

It was
raining, so Trayvon took a shortcut on his way back home, she said. That's when he revealed 'a man was watching him'.

Jeantel said she told Trayvon she was worried the man was a rapist. Trayvon said to 'stop playing with him like that'.

She then told the jury - made up of five white women and one Hispanic - she heard Trayvon ask the man, 'Why are you following me?' and that he said, 'What are you doing around here?'

She then said she heard Trayvon’s phone headset fall and him saying: 'Get off!'

When asked about why she lied about not going to the funeral, she said: 'I felt guilty...I was the last person that talked to their son', before breaking down in tears.

Jeantel also said the screaming voice on 911 calls, which she heard through media outlets after her friend's death, 'sounded like Trayvon'.

After Martin's death, Jeantel said she found out about the incident from a friend's text message and decided not to go to his wake because she didn't want to see his body.

At times during her testimony she dabbed away tears, as did the father of Trayvon Martin.

The defense is expected to call her credibility into account after she tweeted about the case and discussed 'getting high' and 'driving drunk'

He would come to her neighborhood to ride bikes and play games, she said. They met in second grade but lost touch until 2006. She denied being his girlfriend as she has frequently been described as up to this point.

Earlier today a neighbor of Zimmerman cried
as she testified about hearing a boy's cry for help shortly before
she heard a gun go off.

But Jayne Surdyka also testified on
the third day of testimony in Zimmerman's murder trial that she heard
multiple gunshots, 'pop, pop, pop'.

Only one shot was fired in the fatal encounter between Zimmerman and 17-year-old Trayvon Martin.

'I
truly believe the second yell for help was a yelp,' said Surdyka, who
later dabbed away tears as prosecutors played her frantic 911 call. 'It
was excruciating. I really felt it was a boy's voice.'

'It shows the context in which the defendant sought out his encounter with Trayvon Martin,' he said.Zimmerman, whose father is white and whose mother is Hispanic, has denied the confrontation with the black teenager had anything to do with race, as Martin's family and its supporters have charged.

There were emotional scenes in the Sanford courtroom yesterday as jurors were shown graphic pictures of Trayvon's body - including close-ups of the gunshot wound - after he was killed.

His parents Tracy Martin and Sybrina Fulton left the room shortly after the harrowing images were projected onto a large screen.

Sanford Sgt Anthony Raimondo was called to the stand yesterday afternoon - the same sergeant who was described in opening statements as the one who tried to 'breathe life' into Trayvon.

Under cross examination he explained what he found after arriving on the crime scene 'within five minutes' of when the 911 call was made.

He described in detail how he found Trayvon's body lying face down on the grass with his hands underneath him.

He checked for a pulse twice and turned him over to perform CPR. As he tried to revive the teen, he told the court he could hear bubbling sounds coming out of Trayvon's chest as he attempted to resuscitate him.

He asked people who had come from their homes after the shooting for Saran wrap and Vaseline to plug the wound. One of the bystanders brought him a plastic bag.

Later, jurors were shown pictures of the Arizona fruit juice can and pack of skittles the 17-year-old had just bought in the 7/11.

Crime scene technician Diana Smith presented several pieces of evidence to the court room as well as describing the area where she put yellow markers down.

Prosecutor John Guy asks Smith to point out and describe each item at the scene - which included a flashlight, cell phone and plastic bag as well as the skittles and juice can.
